However, fully consideration of special structure and physiological function of CRP is critical to investigate whether CRP provide protect effect or pathogenic effect in the progression of atherosclerosis. CRP is a member of pentrxins family, which consists of five identical, noncovalently associated 23-kDa protomers arranged symmetrically around a central pore with a 102 A external diameter. Each protomer has a recognition face with a phosphocholine binding site consisting of two coordinated calcium ions adjacent to a hydrophobic pocket. The opposite face of the pentamer is the effector face, where complement Clq binds and Fc receptors are presumed to bind. A cleft extends from the center of the protomer to the central pore of the pentamer. Both faces ofpentamer form a special bi-phase structure: one face is the ligand recognition phase, which can recognize apoptosis cells and enzyme modified low density lipoprotein in which PCh is exposed.

CRP是一种五聚体蛋白，外径为102 A，由5个相同的单体以非共价键结合，形成双面的环形结构，每个单体的配体识别位点或受体结合位点分别位于五聚体两个平面上，分别组成配体识别相和效应器相，从而构成特殊的二相性结构：一面为配体识别相，含有磷酸胆碱(phosphorycholine，PCh)结合位点，能够使CRP识别在病理条件下暴露出PCh的凋亡细胞、酶修饰低密度脂蛋白(enzyme modified low density lipoprotein，E-LDL)等。E-LDL是天然低密度脂蛋白(native Low density lipoprotein，N-LDL)在多种蛋白酶，如胰蛋白酶、神经氨酸酶、胆固醇酯酶等作用下的代谢产物，其主要特点是结构发生改变(N-LDL大小均匀，平均直径250±30 A，E-LDL大小差异极大，直径为100-2000 A)，暴露磷酸胆碱位点，能够被CRP识别；另一面为效应器相，能够与巨噬细胞、单核细胞表面受体FcγRⅡa结合，介导巨噬细胞、单核细胞识别及吞噬凋亡、坏死细胞作用。
